Key takeaways
- Sitting increases disc pressure.
- Support your lower back.
- Keep feet flat, knees level.
- Remove your back-pocket wallet.
- Get up every 30 minutes.
Many people feel sciatic discomfort most when they sit. The good news is that a few adjustments can make sitting much more comfortable.
Why sitting affects the sciatic nerve
| Factor | Effect |
|---|---|
| Disc pressure | Sitting loads the lower spine's discs more than standing |
| Tight hip flexors | Shortened muscles pull on the pelvis and back |
| Piriformis pressure | Sitting on hard surfaces or a wallet presses the buttock |
| Less movement | Muscles stiffen and circulation slows |
The comfortable sitting checklist
Feet and knees
Feet flat on the floor or a footrest, knees at or slightly below hip level.
Back
Sit back in the chair with a small cushion or rolled towel in the curve of your lower back.
Screen and arms
Screen at eye level, elbows close to your sides at about 90 degrees.
Pockets
Remove your wallet and phone from back pockets.
Movement
Stand, stretch or walk for a minute or two every 30 minutes.
In the car
Adjust the seat so you can reach the pedals without stretching, recline slightly to about 100 to 110 degrees, use lumbar support and stop every hour on long drives to walk and stretch. Supporting your nerves nutritionally can help too: Sciatilief combines magnesium glycinate, alpha lipoic acid, CoQ10, L-carnitine, turmeric and butcher's broom to support sciatic nerve comfort.

Common questions
Why does sitting make sciatic discomfort worse?
It increases disc pressure, tightens hip muscles and reduces movement.
What is the best way to sit?
Feet flat, knees level, lower back supported and screen at eye level.
Does a back-pocket wallet matter?
Yes, sitting on a wallet can press on the buttock and sciatic nerve.
